摘要： An on-vehicle display apparatus includes a motor, a gear train, a threaded rod, a slider screwed to the threaded rod, and a display main body rotatably connected to the slider. The lead angle of the threaded rod is set greater than the friction angle thereof. The gear train includes first and second gears facing each other. Protrusions provided on one of the first and second gears are fitted in recesses provided in the other. A spring member elastically urges the first gear toward the second gear. A detection sensor detects the size of an external force on the basis of the displacement of the first gear against the spring member in the axial direction. The motor is controlled on the basis of the detection result of the detection sensor such that the display main body is moved away from the external force.

摘要： A shutter member is provided so as to be capable of moving in association with a roller bracket. The shutter member rotates by a predetermined range in association with the rotation of the roller bracket, and then a projection of the shutter member is pressed in a Y1 direction by a shutter pressing portion provided on the right side slider. Accordingly, the shutter member is rotated clockwise, and an opening and closing panel portion of the shutter member closes an insertion port from the inside thereof. Therefore, the insertion port is closed reliably by the shutter member, so that insertion of another disc from the insertion port into the interior of the apparatus while the disc is rotating is prevented.

摘要： A head feeding mechanism which includes a screw shaft adapted to rotate in the normal and reverse directions using a motor as a drive source, a nut member engaged with the screw shaft, and a spring member connected to a head and adapted to elastically press the nut member against the screw shaft and which causes the head to reciprocate in the thrust direction of the screw shaft through the intermediation of the nut member through rotation of the screw shaft. The nut member has a substantially cylindrical female screw engaged with a male screw of the screw shaft, and the nut member is elastically biased in both the radial direction and the thrust direction of the screw shaft by the spring member. In this construction, if the elastic biasing force in the radial direction of the spring member holding the nut member in pressing contact with the screw shaft is set small, the female screw of the nut member does not move over the male screw of the screw shaft, so that a small torque suffices for the motor rotating the screw shaft, which is effective in achieving a reduction in the size of the motor and the entire head feeding mechanism including the motor. Further, the thrust play of the nut member due to backlash is removed, making it possible to prevent a malfunction attributable to external vibration, such as a dropout.
摘要翻译：一种头进给机构，其包括：螺丝轴，其适于使用电动机作为驱动源在正反方向上旋转;螺母构件，其与所述螺杆轴接合;以及弹簧构件，其连接到头部并适于弹性地按压所述螺母构件抵靠螺杆轴，并且通过螺杆轴的旋转通过螺母构件使头部沿螺杆轴的推力方向往复运动。螺母构件具有与螺杆轴的外螺纹接合的大致圆筒形的内螺纹，并且螺母构件通过弹簧构件在螺杆轴的径向方向和推力方向上弹性偏置。在这种结构中，如果将保持与螺杆轴压接的螺母构件的弹簧构件的径向弹性偏压力设定得较小，则螺母构件的内螺纹不会移动到螺杆轴的外螺纹上，因此能够使旋转螺杆轴的电动机具有小的转矩，这对于实现电动机的尺寸的减小和包括电动机的整个头部进给机构是有效的。此外，除去由于齿隙引起的螺母构件的推力作用，使得可以防止由于外部振动（例如压差）引起的故障。

摘要： A head feeding device includes a screw shaft having a thread groove formed with a predetermined pitch, a driver for turning the screw shaft, a head guided in the axial direction of the screw shaft by a shaft bearing sliding on a surface of the screw shaft, and an engagement member that engages in the thread groove of the screw shaft and converts the turning force of the screw shaft into the axial head moving force. A second groove for containing a lubricant is formed on the screw shaft having the same pitch as that of the thread groove. The second groove retains lubricant scraped out of the thread groove by the engagement member. Therefore, lubricant is reliably supplied to the sliding surfaces between the screw shaft and the shaft bearing, thereby eliminating problems caused by increased friction or seizure, and thereby improving the head feeding accuracy.

摘要： A car-mounted disc player with an elastically supported drive unit including a turntable and a pickup; a clamper-supporting member rotatably supporting a clamper; a clamp mechanism for activating the clamper-supporting member to move toward or away from the drive unit so as to clamp or unclamp a disc between the turntable and the clamper; a lock mechanism for bringing the drive unit in a locked state or an unlocked state with respect to the chassis; and a change-over mechanism for activating the clamp and lock mechanisms. During change-over operations of the change-over mechanism for activating the clamp and lock mechanisms, the change-over mechanism can be halted at a half-locked position where the drive unit is brought in the locked state while the disc is kept in a clamped state by the turntable and the clamper.

摘要： A disc device in which a clamping member for supporting a clamper is pushed against a supporting portion by a holding elastic member. At the side opposite the supporting portion, a clamping elastic member is provided between a drive chassis and the clamping member. The distance from a supporting fulcrum to a portion upon which the elastic force of the clamping elastic member acts is greater than the distance from the supporting fulcrum to a portion upon which a clamping force acts, so that the elastic force of the clamping elastic member for setting the clamping force can be small. Therefore, a large localized force does not act upon the clamping member from the clamping elastic member. In a conventional vehicle-mounted disc device, a spring having a large elastic force is used to exert a clamping force to clamp a disc by a clamper. Therefore, a large localized force acts on a clamping member for supporting the clamper. In addition, a large force is required to lift the clamping member. The present invention solves these problems.
摘要翻译：一种盘装置，其中用于支撑夹持器的夹紧构件通过保持弹性构件被推靠在支撑部分上。在支撑部分相对的一侧，在驱动底座和夹紧构件之间设置夹紧弹性构件。从支撑支点到夹紧弹性构件的弹力作用的部分的距离大于从支撑支点到夹紧力作用的部分的距离，使得夹紧弹性构件的弹力用于设定夹紧力可小。因此，大的局部力不会从夹紧弹性构件作用在夹紧构件上。在传统的车载盘装置中，使用具有大弹性力的弹簧来施加夹紧力以通过夹持器夹紧盘。因此，大的局部力作用在用于支撑夹持器的夹紧构件上。此外，需要大的力来提升夹紧构件。本发明解决了这些问题。

摘要： A disk apparatus wherein a cleaning member and a shutter for cleaning and covering an optical head are actuated by the motor used to drive a head positioning member (such as a screw shaft). During a reading operation, a screw shaft is rotated by a motor in a clockwise or counter-clockwise direction, and a carriage meshed with the screw shaft is driven to move an optical head over a disk. When the reading operation is stopped, the optical head is moved by the screw shaft to a retracted position. After the optical head is fully retracted, the screw shaft is further rotated by the motor and the screw shaft is then moved along its axis relative to the optical head. As the screw shaft moves, it pushes against a drive member, which in turn causes a support member to rotate so that the optical head is cleaned by a cleaning member provided on the support member, and is covered by a shutter, which is also formed on the support member.

摘要： A disc device in which, when a driving unit including a self-chucking-type rotatable table is moving towards the front, a disc is transported by a transporting roller, and is sent between the rotatable table and a guiding plate. At this position, a driving unit moves upward, causing the disc to be sandwiched between the rotatable table and the guiding plate, so that the disc is clamped to the rotatable table. Thereafter, the driving unit moves downward, and moves further towards the back side of a housing in order for the disc to be drawn into the housing. A disc device using a self-chucking-type rotatable table requires a complicated mechanism for pushing a disc against the rotatable table, so that it is difficult to reduce the size of the disc device.
